I recently responded to a message on LinkedIn from a regular reader of this blog. He asked several questions which I will answer over the course of several posts. As part of his first question, he described a strategy report that his group is producing. The audience for this strategy report considers ITIL important to the future of their business, and so he must describe which ITIL processes his data center operations group works most closely with.

In the last two posts I discussed aspects of services in the context of some landscaping work that I’m having done. This is clearly what many people would call a “non-IT example.” I often use similar examples in my classes. However, I might initially describe an example that seems unrelated to IT, but will conclude with a challenge to students. That challenge is, “identify the IT in this example.” The truth of the matter is that most businesses these days are underpinned by some form of information technology. In fact, technology has become so ingrained into everyday services that often even the service providers themselves don’t realize how technology supports their business.

As mentioned in last week’s post, interviews that require ITIL Intermediate level knowledge will most likely be targeted to specific process areas and activities. If I interviewed someone for a job that required ITIL Intermediate level knowledge, in addition to other questions about the specific technical responsibilities of the job, I might ask the following questions:

IT departments have multiple opportunities and challenges as a result of the Bring Your Own Device (BYOD) invasion. The most common opportunity is to reinforce enterprise network security from both the inside and the outside. Supporting BYOD also offers more monitoring and tracking of activities that provide a more detailed view of network traffic flow. Alternatively, it will be a challenge for some IT departments to give up control over which devices may access their enterprise network. Another challenge will be to have the users doing configurations for network access, which adds human error to a crucial part of the process. The opportunities and challenges BYOD represents are real. Enterprises must make their network infrastructure BYOD ready to meet the onslaught.

Your business has been hacked, leaving you with a persistent bot; now what? In this hour-long webinar, security expert David Willson will discuss ways you can eliminate the threat in an act of self-defense or defense of property. As new laws are explored, old ones amended, and solutions sought, you'll take a look at thinking outside the box to give the good guys the advantage-or at least a fighting chance.

In this hour-long webinar, security expert and Global Knowledge instructor Phillip D. Shade will provide insight into the emerging network security science of network forensics analysis, a.k.a. security event analysis and reconstruction. Using case studies, you will examine the role of data retention in network forensics analysis, and you will learn about applying forensics analysis techniques to handle application-based attacks, VoIP call interception, and worms, bots, and viruses.

An attacker needs to destroy evidence of his presence and activities for several reasons like being able to maintain access and evade detection (and the resulting punishment). Erasing evidence of a compromise is a requirement for any attacker who wants to remain obscure and evade trace back. This usually starts with erasing the contaminated logins and any possible error messages that may have been generated from the attack process.
